Figure 18
Time-averaged neutron energy spectra at the sample and the scattering characterization system with a Y2O3 sample in the Geant4 simulation using a 2 MW source power, 3 mm height and diameter sample size, and 60 arcmin sample mosaicity. Incident beam on sample (in blue), beam transmitted through the sample (in orange), beam on the set of analysers for 2.7 meV neutrons (in green), beam on the set of analysers for 5.0 meV neutrons (in red), neutrons hitting the detector triplet for 5.0 meV (in purple), beam transmitted through all sets of analysers (in brown). The lines are only joining the points. |
